1. The problem statement, all variables and given/known data You are given a vector in the xy plane that has a magnitude of 85.0 units and a y component of -50.0 units.? The two possibilities for its x component are + and - 68.74. Assuming the x component is known to be positive, specify the vector which, if you add it to the original one would give a resultant vector that is 70.0 units long and points entirely in the -x direction. Magnitude = ? Direction = ? degree 2. Relevant equations 3. The attempt at a solution I found the first part of the problem which was "What are the two possibilities for its x component?" But I can't get the right answer for the second part. I'm doing this online so I know if I get it wrong or right.
